My brother lost his phone in/near the Termini Station on Sunday, November 20th - 16:00 to 16:50.
The phone's model is a one plus 3, with it being gold color at the back.
Can you please check if one has been reported found? Likely place to have dropped the phone would be near the trenitalia ticket purchased at 16:32, which was at the immediate left of the entrance to the termini station (where the buses to the airport depart).
Phone has precious memories in them. I'm hoping it wasn't pick pocketed, and instead just lost. :-(
